Read more and study any and all pictures you come across, doesn’t matter if it’s dual plane, single plane, high dollar port work by experienced porters, or intakes for other makes. There’s endless pictures of ported intakes out there. Books as well. Study what you can on plenum work, the roofs of the runners as they enter the plenum/opening, the inside wall of each runner, and how to gasket match, how far up to go with the specific intake you may decide on. On a cleanup and/or “applying the basics” some may need more attention, some not so much. If you’re starting out you are not going to be hogging out anything, welding, using epoxy etc. Just employing the basics.
